METAL RIM AND DISK WHEEL.

Original application filed July 26, 1920, Serial No. 398,927. Divided and this application filed June 16,

1921. Serial 1T0. 478,029.

To all whom it may concern Be it known that I, WILLIAM E. WILLIAMS, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Im rovements in Metal Rim and Disk Wheels, 0 which the following is a specification, reference being had therein to the accoi i ipanying drawing.

is invention re ates principally to the construction of the rim and adjacent portions of a metal disk wheel, the construction being that shown in my application Serial Number 398,927, filed July 26, 1920, of which this application is' a division. The object is to provide a simple construction that will give elasticity and unusual strengthin this portion of a wheel and to secure ease of re-' pair and ready cleaning by having a nearl unbroken surface which can be wiped o quickl when desired.

In t e accompanying drawings:

Fi 1 is a view of a small portion, or seetor o the face of a wheel. Fig. 2 is a radial section of the wheel.

Fig. 3 is a section on the line 3-3, Fig. 1, with parts separated. 1

Fig. 4 is a view in the direction of the arrow of Fig. 3. In these views, 1 designates the main annular portion of a wheel rim having a broad flange 6 projecting obliquely inward'with its inner marginal portion bent sharply outward to form a. more oblique narrow annular rojection 7. Against the flange 6 rests a like-inclined flange 9 of a companion member 2 this latter flange having an oblique edge iace fitting the projection 7 and secured to the flange 6 by convex-headed bolts '12 having a square body and engaged by nuts 13. These bolts are non-revolub e in the flange 9 to which they are permanently fixed by' swaging over the an les of the bodies as in-.

dicated at 15. The olt holes in the flange Bare cut away at 16, 17 to receive the portions 15, to avoid shearing strains on the bolts which thus bear ulllng strains onlp, and to facilitate assem ling. An inward y dished wheel "sk 3 has its peripheral zone outwardly inc and" is bent sharply inward near its mar in to form a shouldersupporting the projection 7 and then carried outward y, with respect to the wheels center, along the flange 6 to the ed by reason of this dishing ly extending flange inclined to the plane of the wheel and provided with bolt-receiving perforations, of a companion ring member havin a similarly inclined inwardly extending flange carrying permanently attached bolts smaller than said perforations through which they pass in securing the two rim members together. v

3. In a wheel of the class described, main and auxiliary rim members having inwardly projecting anges fitted to ether and inclined to the plane of the wheel, the flange of the main member being bent laterally near its margin to fit an inclined edge face of the companion flange.

4. A, rim composed of a main annular member and a companion annular member, each provided, at some distance outward] from the central load plane "with an inwar ly extending flange inclined outwardly with respect to t of the main member having elongated perforations, and a series of-bolts fixed to the flange of the com anion member and adapted to pass throng said perforations and to receive clamping nuts.

5'. In a wheel of the class described, a rim consisting of a main portion and a companion flange" portion, each portion having a flange e xtendin'g' inwardly with respect to the wheels center, in combination with a disk secured on the inside-of the flange of the main ortion, and a series of bolts clamping the sisk and flanges togiether and having rounded heads exposelg gofn the outer, side of the. rim, with nuts engaging the bolts on the inside of the wheel.

6. A rimcomposed of main and companion parts each having'an inwardly extendlng inclined flange fitting against the other flange,

e plane ofthe wheel, the flange w the flange of tli'ecompanion flange bearing a.

series of ermanently attached bolts passing throu h arger apertures in the-other flange,

where y the parts are readily assembled al- I though the bolts are inclined with respect to their direction of movement in assembling. 7. In a wheel of thezfelass described, a bolted-on flange forminga part of the rim, said flange seoured to the mam portion of the rim-through-a series of bolts, and the said 10 bolts firmly fixed in said bolted-on flan e by having portions of their bodies swage into engagement with said flange and the bolt ho es in the other flan e beingv materially larger than the bolts w ich enter them.

. .8. The combination-with a main rim membar and a companion member, each having a flange extending toward the center of the wheel and obliquely outward with respect to the plane of the wheel, of bolts binding said flanges together, and a wheel disk supporting the inner edges of the inwardly extending flanges and itself extending outwardly from saidedges alongside the flanges, to meet the main rim member, thereby supporting it in two different planes.

In testimony whereof I hereunto aflix my signature.

WILLIAM ERASTUS' WILLIAMS.
